Change map key type in AnnotationDescriptor.getAllValueArguments

Turns out, only the parameter's name is needed at all usages of this
method. Such a map is both easier to use (no need to call
ValueParameterDescriptor.getName) and easier to construct (no need to
resolve annotation class, its constructor, its parameters). In this
commit, only usages have changed but the implementations are still using
the old logic, this is going to be refactored in subsequent commits
